I have read the link below from 2010 on this forum regarding oil use for 4 runner.

http://www.toyota-4runner.org/gener...y-0w-20-synthetic-oil-explanation-inside.html


I started a thread on Bob is the oil guy. 0W20 oil - Bob Is The Oil Guy



It seem that most follows the manufactures recommendation with religious adherence, even when the conditions of usage are different and the owners manual specifically allows for oils other than 0W-20.

Has anything changed from first posted link on this forum regarding oil recommendation

Below is my post from BITOG:

Does 0w20 weight syn. oil really provide better bearing lubrication than heavier weight oil? With ambient temps 65 degrees to over 100 degrees.

I have 2012 toyota 4runner and it recommend the 0w20. Seems like reason are based on marketing, emissions, and fuel mileage. As well as fact that was probably the oil the engine was tested with.

So wouldn't a heavier syn be better?

Find owners manual.

Find page that indicates what oil to use.

Use that oil.

I did and you read my post referenced above you would see what I'm talking about.

Page 637.

Engine oil selection
"Toyota Genuine Motor Oil" is used in your Toyota vehicle. Use Toyota approved "Toyota Genuine Motor Oil" or equivalent to satisfy the following grade and viscosity.

Oil grade: ILSAC multigrade engine oil

Recommended viscosity: SAE 0W-20

It then has a chart that has arrow that shows 0W20 can be used when outside temperature is from -20 degrees F to 100 degrees F.

SAE 0W-20 is the best chioce for good fuel economy and good starting in cold weather.

If SAE 0W-20 is not available, SAE 5W-20 may be used. However, it must be replaced with SAE 0W-20 at the next oil change.

Oil vliscosity (0W-20 is explained here as an example):

*Oil viscosity (0w-20 indicates the characteristic of the oil which allows cold startability. Oils iwth a lower value before the W allow for easier starting of the engine in cold weather.

*The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a higher value) may be betterr suited if the vehicle is operated at hgih speeds, or uder extreme load conditions.

My vehicle will be operated in temps exceeding 100 degrees F and never in temps below say 20 degrees F.

I think it is clear they are not mandating the use of 0W-20 for all users. Any contray opinions?
 
I don't understand oil, it's like a religion to some of you guys. You've obviously got your own opinion, why are you trying to get other owners to agree with you?

Run what you want, man. If your engine starts making funny sounds, run something else.
 
I will give you one reason for 0W-20: 65 degrees is still a cold start. Starting and the period until the engine is up to operating temp is the hardest on engine. I will tell you the same thing as I do everyone else who second guesses the specialists in this field: regardless of who or why someone at Toyota made this recommendation they stand behind their words with a warranty.
 
Cold start is a cold start even at 100 deg! The Toyota 0W-20 oil is an excellent oil.

Why would you use something heavier?

What conditions are you in specifically that would warrant heavier oil?

Do you want an oil that is heavier at start up or at temp? ie a 5W-20 or 0W-30? Why? Many 30 weight oils shear into heavy 20 weight oils anyway.

We are in a new and exciting age of motor lubrication, the quality of base stocks and additive packages now would have been called space age a few decades ago! All this 20 weight drama reminds me of 10W-30 vs 5W-30 many years ago and look how that turned out!

I would run the Toyo 0W-20 in my 4.7L and sleep well at night but I have many years of M1 stocked up.

Two very good points. Ok so 0W for weight.

Let me ask you this. What do you think about an oil with a higher viscosity like OW-40. This is what I use in two of my newer Mercedes vehicles with much lower mileage than my other MBs.

To the extent I get better mileage with 0W-20 I am not concerned.

Dont forget that an engine is not an engine. Many Euro cars are spec'd for heavier (XW-40) oils are DI, high comp, or have other design or operational differences (like crazy complicated variable valve mechanisms) that shear an oil down over the life of the OCI. Not to mention an engine, oil pump, oil passages, take up with a certain weight for flow properties. Using a thicker oil may very well starve your engine of oil at certain places and at certain operating loads.

ETA: I have learned a lot from BITOG in the years I have been over there.

Are there any other car makers who have found the need to spec out their very own motor oil for their cars' engines ? I know about Honda specific PS fluid, and the old days of several flavors of ATF. But engine oil ? Weird.
 
Ok I have seen the light as it relates to 0W oil.

I wonder how long the 0W-20 oil has been out. Was it made at the request of Toyota?

i'm fairly certain the OP means the Toyota 0w-20. and i believe the answer is that, yes, it was developed for Toyota according to the comapny's specifications.

Yes correct as to Toyota 0W-20.

Is the 1GR-FE motor in my 2012 4runner a fairly new motor as far as years in service?

It would be interesting to know what Toyota had as criteria for new oil. More protection for certain parts that were wearing at unacceptable rates, emissions issues, mileage issues.
 
So i have been getting my oil changed at the dealership every 5-7500 miles with 0w-20. Today was the first time I brought my 4runner to my personal mechanic instead of the dealership and he calls me and tells me that when he drained the oil, it came out milky in color and with a metallic glitter??? This doesn't make sense because my motor has only 55,000 miles on it and it has only had the oil changes at the dealership since new.

Anyone else had any issues with their motor???

Thanks

My first question to him would be "Take a sample and we'll send it in." If he says he didn't save any of it for a sample then you have a terrible mechanic. If he did then send it in. If it comes back bad then you have recourse against the dealership. If not then you are up the proverbial creek without a paddle. Sorry.

To answer your question, no. Very few motor problems from the thousands of owners.

Post pics of the oil and then post the sample when it comes back.
